Right-handed, but play blitz chess left-handed.

Hello. As a Tanki Fund participant, I received the containers, Crisis, Armadillo, Pulsar (Tesla), Helios, Vacuum Shell. However, I am MISSING the following prizes: Hammer (LC and Magnetic Pellets augment) and Scorpion (Swarm Augment - I do have the Scorpion turret). Was there a rank limit to these augments? I was Sergeant Major at end of the Tanki Fund and am now WO2 and I've seen others at my rank with the Swarm augment. Is there a glitch or rank restriction? Please help. Thanks.
